My water broke with the first two, totally unmistakeably. Third was born in the caul. 37w4d, 38w1d, and 38w6d.
Today I am 36w3d and on my way to the bathroom this morning I had a little gush of something. Definitely not pee, I was holding that very well, and I had peed only a couple hours earlier. But nothing since. Well, I'm damp, but nothing flowing.
I have ctx almost all the time, so nothing new there.
BUT I can feel something a little different in my vagina.
